The optimum flow channel depth and mass flow rate in 10 different designs of solar air heaters have been obtained. The design variations considered are flat absorber type with and without cover glazings; single, double and triple pass etc. It is found that there exists an optimum mass flow rate...

A detailed theoretical parametric analysis of a corrugated solar air heater with and without cover has been presented. The optimum flow channel depth, at which the maximum heat is available at the lowest collector cost, has been obtained. The effect of collector parameters and operating...

Purpose To better understand bioenergy's role in sustainable rural development and cleaner environment, it is necessary to place it in a local regional context. This paper aims to provide a conceptual approach for biomass-based energy self-sufficiency in rural areas of developing and...
